Question

question 5
which is the building block for carbohydrates?
○ nucleotide
○ amino acid
○ glycerol & fatty acid
○ monosaccharide
question 6
which solution will react with a monosaccharide (simple sugars)?
○ sudan iv
○ biuret solution
○ benedicts solution
○ iodine solution

Explanation:

Question 5

Nucleotides are for nucleic acids, amino acids for proteins, glycerol & fatty acids for lipids. Monosaccharides are the monomers (building blocks) of carbohydrates.

Sudan IV tests lipids, Biuret tests proteins, Iodine tests starch (polysaccharide). Benedict's Solution tests for reducing sugars (like monosaccharides) by changing color.

Answer:

monosaccharide
